It sounds suspiciously like it could be an induced current to me. I guess the wires don't happen to be moving through a magnetic field do they? Or sited in a changing magnetic field of any description?

Is there any possibility of RF interference generating an EMF in the wiring?

if you energize one side of a twin wire without an earth you will get an induced voltage in the other cable as the rotating magnetic flux in the live cable is in effect being "cut" by its twin
( this is common where you have a redundant unearthed cable in a multicore )

Yes, mutual induction we call it in Physics. No doubt Electricians have a completely different name for it. If he gets it running just right, then he could build his own transformer!

This makes a change to discussing the wiring of plugs...

if there is a Neutral fault on the main switchboard thats could also be a possible cause also due to the MEN if the place either side of you also has a neutral fault you may be picking up fault currents from the supply worth having it checked out. Make sure your earthing is good with an Earth Rod driven in the ground. DONT disconnect any bare earth wires EVER at the switchboard

Hi Arthur

If there was a neutral fault, more of the lights would be lighting up dimly anyway, most electronic stuff you play up also,
Could it be something simple like a faulty switch breaking down ???

Keep things simple get the place tested.

your right regarding the Neutral more lights would be affected, the only thing i can think of maybe the light switch is faulty may i ask is there an earth connection present if NOT then there may be a problem with parallel faults in some conductors.

The 5 lights are in two sets separately switched: 2 on one and 3 on the other switch: each set are two-way switches.

do both circuits pulse at the same rate ??

Approximately: it's actually quite difficult to see since the effect is so dim. You have to be looking through peripheral vision to make out the blinks, in pitch darkness. They come about every 12 - 15 seconds and aren't synchronised so I guess the answer is a very slight voltage in a wire for some reason.

going to stick to induced voltage in the switch wire picked up from the permant phase conductor
